Key updates
IntelliJ IDEA 2023.2 introduces AI Assistant, which offers integrated AI chat and can do things like automatically write documentation comments for you, suggest names, generate commit messages, and more. Access to the AI capabilities is limited for now and requires you to install the AI Assistant plugin and log in to the JetBrains AI service. For more information refer to this blog post.
The IntelliJ Profiler has added in-editor performance hints, which enhance your profiling experience by providing easy-to-interpret color-coded annotations right in the gutter.
Integration with GitLab streamlines your development workflow by enabling the Merge Request functionality directly in the IDE. Learn more.
